LAST YEAR: Dolphins had new coach (again) and new quarterback (again), and may have finally found some stability with both jobs. Joe Philbin won favorable reviews from players in first year as NFL coach, and rookie QB Ryan Tannehill played well and showed progress. Lack of playmakers was biggest problem. No WR scored more than one touchdown for offense that ranked 27th, and defense tied for fourth worst in takeaways. Miami endured fourth consecutive losing season, franchise's worst such stretch since pre-Don Shula 1960s.
